Specification of Letters Patent.

Application filed January 30, 1911.

Patented Oct. 31., 1911.

Serial No. 605,442.

An important object of this invention isto provide a vehicle spring ofsimple construction, which is highly capable of absorbing all primaryand rebound shocks transmitted to an automobile or the like.

A further object of this invention is to provide a spring of the abovecharacter, which is strong, durable and not liable to derangements.

Other objects and advantages of this invention will be apparent duringthe course of the following description.

In the accompanying drawings forming a part of this specification, andin which like numerals are employed to designate like parts throughoutthe same, Figure 1 is a side view of my vehicle spring structure. Fig. 2is a horizontal sectional view taken on line 2-2 of Fig. 1. Fig. 3 is acentral vertical sectional view taken through the spring structure. Fig.4 is a bottom plan view of the spring structure. 7

In the drawings wherein is illustrated a preferred embodiment of myinvention, one corner of a vehicle frame is shown, comprisinglongitudinal and transverse beams 1 and 2, respectively. These beams areconnected by a plate 3, which is bolted or otherwise secured to theframe, as shown at 4. The transverse beam 2 runs laterally beyond thebeam 1, to form an extension 5.

Disposed near each corner of the frame of the vehicle, is a preferablycylindrical casing 6, provided with an arm 7, which is preferably formedintegra'l therewith, as shown. This arm is bolted to the beams 1 and 2,as shown at 8. The lower end of the casing 6 is formed open, as shown,and said casing is provided near such lower end with an inwardlyextending horizontal annular flange 9, from which depends a preferablycylindrical tube 10. This tube extends below the lower end of the casing6, forming therewith an annular space 11. Longitudinally movably mountedwithin the depend ing tube 10 is a vertical tube 12, having its upperend closed by a wall or cap 13, provided with an opening 14 formedtherethrough. The opening 14 loosely receives a vertical pin 15, whichis rigidly connected wit-ha preferably circular wall 16, as shown. Thewall 16 is formed upon an annular flange 17 which is formed integralwith and extends upwardly from the upper closed end 18 of the casing 6.The flange 17 forms an internal recess 19, for a purpose to be de-'scribed. The lower end of thepin 15 is provided with a head 20, engaginga compiessible coil spring 21. This coil spring surrounds the lowerportion of the pin 15 and engages the wall or cap 13. The tube 12 isprovided near its lower end with a socket 22, comprising horizontal andvertical flanges 23 and 2 1, respectively, which are preferably castintegral with said tube, as shown. A compressible coil spring 25surrounds the tubes 10 and 12 and has its upper and lower ends disposedrespectively, within the recess or socket 11 and the socket 22.

The lower end of the tube 12 is provided with a curved recess 26, forthe reception of an axle 27. This axle is held in place by pairs ofclamps 28, which are connected with pairs of ears 29, by bolts 30. Theears 29 may preferably be cast integral with the tube 12 and flange 23.

A compressible coil spring 31 surrounds the upper portion of the pin 15,the upper end of said spring fitting within the recess 19 and the lowerend thereof engaging the wall or cap 13, as shown.

In the operation of the spring structure, the vehicle frame beingsupported by the casing 6 and the tube 12 by the axle 27 all primaryshocks will be absorbed by the large coil spring 25. The shocks ofrebound will be absorbed by the coil spring 21. The coil spring 31 aidsthe spring 25 in absorbing the primary shocks.

I wish it understood that the form of my invention herewith shown anddescribed, is to be taken as a preferred example of the same, and thatcertain changes in the shape, size and arrangement of parts, may beresorted to without departing from the spirit of my invention or thescope of the subjoined claims.

Having thus described my invention, I

second tube slidably mounted Within the first named tube, a coil springsurrounding said tubes, a pin connected with said casing and extendingWithin the second tube, and springs surrounding said pin above and belowthe upper end of said second tube.

2. In a device of the character described, a casing provided interiorlythereof With a depending tube having a less area in crosssection thansaid casing, to form a space between said tube and easing, a second tubefor insertion Within the first named tube and provided near its lowerend With a socket, a spring surrounding said tubes and having its endsdisposed Within the socket and space, a pin connected With said casingand extending Within the second named tube, and a spring to becompressed by said pin and having engagement With the upper poi:- tionof the second named tube.

3. In a device of the character described, a

tube, means to attach the same to the axle of a vehicle, a second tubeslidably mounted upon the exterior of the first named tube, acompressible coil spring surrounding the first named tube to oppose thelongitudinal movement of the second named tube in one direction, thefirst named tube having its upper end formed partially closed, acompressible coil spring disposed within the I- first nained tube andWithin the first named spring, and means connected with the second namedtube including a pin, to compress the second named spring upon the1ongitudinal movement of the second named tube in one direction.

In testimony whereof I afiix my signature in presence of two Witnesses.
